To all whom it may concern.

Be it known that T, MICHAEL J. RILEY, a citizen of the United States,residing at East Cleveland, in the county of Cuyahoga, State of Uhio,have invented certain new and useful Improvements in Bolt Machines, ofwhich the following is a specification.

While in some aspects of more general application the invention relatesparticularly to a machine which will automatically size under the headof a headed blank or bolt or which will automatically shave or finishthe top of such head or perform both operations.

n general the invention includes a hopper into which the blanks or boltsmay be thrown promis'cnously. They may be assorted and arranged andpassed from the hopper to a chute at the end of which they may bereceived by suitable mechanism for delivering them into position to begrasped and held or rotated while a cutting device 'may operate on them.

In one aspect the invention includes a spindle provided with a chuck orcollet for grasping the work associated with means for rotating thespindle and operating the collet and cutters which may be moved tosuitably attack the work. The cutters may have movement transverse tothe axis oi the work or parallel thereto or in both directions. Asupport for the work may be provided near the point of attack by thecutting tools. The support itself may have suitable movement to adapt itto the work and to allow of ingress and egress of the work.

One phase of the invention contemplates picker fingers which bring thework into alignment with the collet so that it may be grasped.Associated with the picker fingers may be a positioning device tendingto p shaft. Fig. 16 is a side elevation of the cam properly hold thework before the collet to be grasped. The positioning device may beresiliently or yieldingly mounted. A device may be provided for kickingthe work from the picker fingers in their retracted position and thisdevice ma move with the fin ers.

The spindle may e mounted in a hea adjustable toward and from the pickerfingers and the cutting tools and may be associated with mechanism forreciprocating it and for operating the collet carried by it so arrangedthat when the relative location of the spindle and mechanism has beenonce ,ldetermined the whole may be adjusted as fa unit without varyingsuch relative location.

tions and, therefore, it is not limited to the particular structureillustrated.

The machine comprises a bed 1 on which is supported a drive shaft 2provided with a drive pulley 3. The drive shaft carries a gear 4 whichengages a ear 5 on a jack shaft 6. The jack shaft 6 a so carries a gear7 which engages a gear 8 on a second jack shaft 9. At its inner end thejack shaft 9 carries a bevel gear 10 which engages a bevel gear 11 on atransverse shaft 12' which carries a worm 13 engaging a worm gear 14 ona cam shaft 15. This train of gears may (ill provide for a reduction ofspeed between the drive shaft and the cam shaft and their relativespeeds may be altered by replacing one or more of the gears. Y

The frame of the machine supports a ho per 16 into which headed blanksmay e thrown promiscuously. The hopper 16 is provided with a chopper 17of a well known form to properly arrange the blanks. A roller 18 iscarried by an arm 19 mounted on'a transverse shaft 20 which carries abevel gear 21 engaging a bevel gear 22 on a shaft 23 which also carriesa sprocket 24 driven by a chain 25 passing. over a sprocket 26 on thecam shaft 15. As the arm 19 rotates it causes the roller 18 to wipe theare shaped bottom 27 of the chopper 17, thereby causing it to rise andfall in the hopper to arrange the blanks in the well known way. spring23 on the shaft 23 allows the sprocket 24 to rotate on the shaft torelieve the mechanism should the chopper stick or be locked by misplacedblanks. The blanks are arranged in the chopper so as to hang by theirheads and at the upper end of the chopper stroke ,those so arrangedslide by gravity into the chute 28 which, as shown, is provided with aguard 29 to keep the blanks in order.

At its lower or outlet end the chute 28 is provided at each side with alock 30, which may be forked, pivoted at31 on the chute side and forcedby a spring 32 into the mouth of the chute so as to prevent blanks fromdropping out. (See Fig. 9.) The outer Sides of the locks 30 are beveledtoward their meeting point and each lock is provided with a set screw33. It will be noted that the locks 30 as shown extend nearly to the topedge of the chute 28 and so engage the lowermost bolt close under thehead and thus the heavier head may be prevented from tipping the bolt orprematurely pulling it from the chute end.

A transverse shaft 34 carried in bearings 35 on the bed of the machinecarries at one end a transverse carrier arm 36. At its other end theshaft 34 carries a pinion 37 which is engaged by a toothed are 38 on oneend of an arm 39 pivoted on the bed at 40. At its other end the arm 39carries a roller 41 adapted to be engaged by a cam 42 mounted on the camshaft 15. The cam 42 is shown in elevation in Fig. 6 and developed inFig. 7. A spring 43 mounted on the bed of the machine bearsagainst thearm 39 and tends to hold the apparatus in position to cause the transferarm 36 to be in a horizontal position. A stop 34 adjustable on the shaft34 engages a web 35 in the bed and limitsthe movement of the transfercarrier arm 36 as. caused by the spring 43 to such as will cause the arm36 tobe substantially horizontal. As it rotates the cam 42 engages theroller 41 so as to cause the toothed arc 38 to rotate the pinion 37 andswing the transfer carrier arm 36 through about 60 upward from thehorizontal to the outlet of the chute .28.

The face of the transfer carrier arm. 36 is beveled at 45 so that as itapproaches the locks 30 the bevels 45 engage the set screws 33 or thebevel face in the locks 30 and so force them to separate against thepressure of the springs 32. The set screws 33 may be A entirely. Thisallows the lowermost blank in the chute to drop by gravity into thecavity 46 on the transfer carrier arm 36. The transfer carrier arm,weighted down by the blank, then returns, under'pressure of the spring43, to its horizontal position, as allowed by the stop 35 and the cam42, carrying the blank with it. If it is found that the blank is heavyenough to depress the transfer carrier arm the spring-43 may be omitted.The locks 30 return, under pressure of the springs 32, to the positionto hold the remaining blanks in the chute as-soon as the beveled faces45 leave the set screws 33.

A longitudinal shaft 47 mounted in the bed of the machine carries arearwardly extending arm 48 on which is a roller 49 en gaged by a cam 50on the cam shaft 15. The shaft 47 also carries a forwardly extending arm51 provided at its forward end .with a fork 52 in which is a transversepin 53. A coil spring 51 fastened to the bed 1 and the arm 51 tends tohold the forward end of the arm substantially horizontal and also holdsthe roller 49 against the edge of the cam 50. In Fig. 1 a coil spring 51surrounding the shaft 47 may augment .or replace the spring 51*. Pivotedon the pin 53 are jaws 54 and 55 acting as .picker fingers for theblank. At their tips the jaws or fingzers 54 and 55 may be forked asshown in ig. 11. The jaw 55 carries a set screw 56 by which the distancebetween the jaws coil spring 61' tending to force together the lowerends of the jawsas allowed by the set screw 56. A coil spring 62surrounds raeaeee the rod 59 between the lug 60 and the jaw 54 and tendsto hold the 'aws as a unit against the set screw 58. The icker finersthus are normally held in xed os1- tions but they are held resilientlyan are capable of suiting themselves either separately and individuallyor as a unit to the pieces and parts with which they co-act or engage.

The transfer carrier arm 36 swings in a plane which is a continuation ofthe plane of the chute 28 and the arm 51 is so mounted and operated thatit may extend the gripper fingers into the same plane. The transfercarrier arm receives the blanks in a substantially upright position andmoves them to a substantially horizontal position. The cam 50-issoformed and timed as to cause the picker fingers made up of the jaws 54and 55 to descend upon and grasp the blank in the horizontal transfercarrier arm 36. The springs 61 and 62 ive sufficiently to allow thefingers 54 an 55 or their forked tips to separate and enter the openings63 through the bevels and the sides of the cavity 46 in the carrier arm36. The picker fingers now may grasp the blank and remove it from thecarrier 36 as the cam causes the arm 51 to rise. The picker fingers riseto allow the transfer carrier arm 36 to move past them toward itsupright position and then the picker fingers move back and furtherdownward past their former position so as to brin the blank about on thelevel with a col et 64. The blank is maintained substantially horizontalso long as it is held by the picker fingers in which position it isgrasped and rotated by the collet.

Pivoted on the shaft 47 is an arm 65 which is connected to the arm 51 bya spring 66. The forward end of the arm 65 may have two fingers 67 and68. The finger 67 extends between the prongs of the forked end of thepicker fingers. The finger 68 extends adjacent the picker fingers on theside away from the transfer carrier arm 36. The spring 66 tends normallyto hold the fingers 67 and 68 of the arm 65 above the gripping surfaceof the picker fingers 54 and so that they are free to grasp a blank. Thearm being loosely mounted on the shaft 47 is free to move with the arm51. When the arm 65 has been carried by the arm 51 to nearly the upwardlimit of movement of the arm 51, a projection 69 from the arm 65 engagesa pin 70 extending from the bed of the machine. At this point the pin 70stops the further movement of the arm 65 and expands the spring 66 asthe arm 51 moves further upward. At this time the grippin jaws 54 and 55wipe past the fin ers 67 an 68 which causes any blank carrief thereby tobe ejected. The normal movement of the picker fingers after receivingthe blank from the transfer carrier 36 is upward a slight distance butless than their full upward movement. This movement does not bring thekick out fingers 67 and 68 into operation. Normally the icker fin ersthen move downward and deiver the lank to the collet. If, however, theblank is misshapen or misplaced or for any reason it is not grasped bthe collet it may be retained in the picker ngers in their finalmovement to their full upward position. In this event the pin 70 causesthe blank so carried to be ejected from the icker fingers which are thusleft empty an prepared to receive the next blank presented to them bythe transfer carrier arm 36.

Extending laterally from the fork 52 which carries the picker fingers 54and 55 is an arm 71 provided with a socket 72 in which is a coil spring73 on which rests a plunger 74. The arm 71 extends from the side of thefork 52 which is away from the transfer carrier arm 36 and the plunger74 is held at such a position that it is approximately in alignment withthe ipping point of the picker fingers 54 an 55. The head of the blanklifted from the transfer carrier arm 36 by the picker fingers 54 and 55rests against the plunger 74 which bein supported by the spring 73allows blanks of varying sizes and variously positioned in the transfercarrier arm 36 to be properly received by the picker fingers 54 and 55.If not grasped by the collet the blanks may be forced, by contact of themoving spindle, against the spring supported plunger 74. The springs 61and 62 allow the fingers 54 and 55 to ive sufiiciently to permit theblank to slide t rough the fingers and compress the spring 73. Thisprevents the a paratus from jamming or becominginjured or disarranged.

The drive shaft 2 carries a long gear which slidably engages a gear 91on a reciprocating spindle 92 carried in an adjustable head 93 restingon the bed of the machine. The long gear 90 may be held in place on thedrive shaft 2 by means of a set screw so that it is adjustable along theshaft. The adjustable head 93 carries a transverse rod 171 on which arethe bearings 172 for a yoke 173 from which extends rearwardly an arm 174carrying a roller 75 which is enga ed by a cam 76' mounted on a drum 77which is adjustably held on the cam shaft 15 by a set screw 78. In ways79 atthe lower end of both arms of the yoke 173 are trunnion blocks 80engaging trunnion pins 81 on a trunnion collar 82. The trunnion collar82 rests between thrust bearings 83 and 84 held by lock'nuts 85 on asleeve 86 adjustably fastened on the spindle by a set screw 87. Thespindle 92 carries at its end the collet 64 and through the yoke lever173 it may be reciprocated in the head 93 so as to cause the collet toadvance and surround the blank brought into alignment with 1t by thepicker fingers 54 and 55. A. stop 88 is held in the base of,..the head93 b screws or bolts 89 in such position as to by the trunnion ring 82so as to limit the forward movement of the collet carried by thespindle. On the rear end of the shaft 171 is fastened by a set screw 94a rearwardly extending arm 95 carrying a roller 96 which may be engagedby a cam 97 car ,ried on the drum '77 on the cam shaft 15. Mounted onthe forward end of the shaft 171 by a set screw 97 is a downwardlyextending arm 98 which engages a link 99 extendin to the left in Fig. 2to engage one arm of t 1e yoke 100 pivoted at 101 to a lug 102 extendingfrom the head 93. The yoke 100 engages a collar 103 of a cone 104 mouned to slide on the s indle 92. Anfgle levers 105 pivoted on a isc 106have orwardly extending arms 187 enga ed by the cone 104. The levers 105have wel ted extensions 108. The disc or collar 106 is pinned to a shaft107 which extends through the center of the spindle 92. The jaws 208 ofthe collet 64 are screwed to the end of the shaft 107 opposite the endcarrying the disc 106. Surro :ndin the shaft 107 is a coil spring 109resting between the inner end of the jaws 208 and the bottom 110 of asocket in the spindle 92. lVithin the shaft 107 and at the end carryingthe collet is a long socket in which rests a plunger 111 on a coilspring 112. The outer end of the plunger 111 normally rests between thejaws 208 of the collet. The outer side of the jaws 208 of the collet arebeveled and engage correspondingly beveled surfaces of a hood 117mounted on the end of the spindle 92.

The spindle 92 is continuously rotated through the gears 90 and 91 andcentrifugal force working on the weighted ends 108 of the levers 105keeps the arms 187 in contact with the surface of the cone 104. Movementof the cone 104 toward the right in Fig. 2 will therefore tend to drawthe disc 106 toward the end of the spindle 92. This will force the shaft107 to the right: in Fig. 12 and co-operate with the expanding spring109 to allow the collet jaws 208 to ride to the right through the hood117 and so open to release a blank and to be in condition to receive ablank. A blank held in the picker fingers 54 and 55 with its headresting against the spring supported plunger 74 will be approached bythe collet as the spindle advances in such a way as to cause the plunger111 to engage the free end of the shank of the blank. The spring 73 isstrong enough to overcome the spring 112. The plunger 111 will thus bedepressed and the spring 112 compressed as a blank is grasped by thecollet jaws 208. When therefore the collet jaws 208 are freed from theblank, the

engaged 4 spring 112 will cause the lunger 111 to e ect the blank frdmthe co et.

-The cams 76and 97 are so arranged and associated with the other partsof the machine that the spindle is reciprocated to approach the blankand cause the collet to surround it. The cone 104 is then shifted tocause the collet to closeand the parts are held in this osition whilethe cutting operation is per ormed, Then the cone 104 is shifted to openthe collet as the spindle recodes to allow the finished blank to beejected and another supplied.

After the blank has been grasped by the collet and the picker fingers 54and 55 have been withdi'awn therefrom a back rest (here shown as rollers119 and 120) may be brought into en agement with the blank preferablyjust below its head. An angle lever 121 pivoted on the frame of themachine carries at its upper end a bolt 1.22. Partly surrounding thebolt 122 is a half bearing in an arm 123 which carries the roller 119.lartly surrounding the bolt 122 is a half bearing of an arm 124 carryingthe roller 120. The split bearings of the arms 123 and 124 engage andlimit the separating movements of the rollers 119 and 1.20 caused bytheir coming in contact with the rotatingb a nk. Set screws 125 carriedby the lever 121 may also be provided to limit. the movement of the arms123 and 124. The lower end of the lever 121 is engaged by a link 126connected to the lower arm 127 of an angle lever pivoted at 128 to thebed of the ma chine. The other arm 129 of the angle lever carries a roll130 which may be engaged by a cam 131 on the cam shaft '15. The form ofthe cam 131 is shown in detail in Fi 16.

' A turn buckle 132 is provided on the lin i 126 to vary and adjust itslength. Between the turn buckle 132 and the bearing 133 in the bed forthe link 126 is a coil spring 134 surrounding the link and tending tohold the roller rests 119 and 120 out of the path of the blank. The cam131, however, engages the roller 130 and compresses the spring 134 andcauses the rollers 119 and 120 to engage the blank and support it as itrotates.

A transverse slide 136 in the bed of the machine is provided at its rearend with a roll 137 which may be engaged by a cam 138 on the cam shaft15. Depending from the slide 136 is :1 lug 139 resting against a coilspring 140 on an abutment 141 in the bed of the machine. The tendency ofthe spring 140 is to force the slide 136 toward the right in Fig. 3 andso keep the roll 137 in contact with its cam 138.

Resting in transverse wa s 142 in the slide 136 is a tool block 143 wich may carry tools 144 and 145 of any suitable shape. To a projection146 on the tool block 143 is pivoted one end of a lever 147. The otherend of the lever 147 extending to the rear esa-see of the machine,carries a. roller 148 riding in a scroll cam 149 on the cam shaft '15.The cam 149 is shown developed in Fig. 17. Passing through alongitudinal slot 150 in the center of the lever 147 is the verticalpivot pin 151 tapped into a plate 220 slidably mounted on the bed of themachine. Rising from the lever arm 147 at eachend of the slot 150 is alug 152 in which is an adjusting bolt or screw 153 provided with a locknut 154. The bolts 153 engage a hearing collar 153 on the pivot pin 151.By turning and adjusting the bolts 153 the position of the plate 220 andthus of the dpivot pin 151 in the slot 150 may be varie and thus ma bevaried the throw of the forward end of t e lever 147 engaging the toolblock 143. When desired either tool may be omitted and the machineoperate with one suitably formed tool.

At the time the blank is delivered to the collet, the roller rests 119and 120 are withdrawn from the path of the blank and the slide 136carrying the tools 144 and 145 is retracted toward the right inFig. 3,After the blank has been grasped by the collet and while being held androtated the roller rests 119 and 120 advance and support the blank andthen the slide 136 is forced toward the blank. At this time the cuttingtools are about in the position shown in Fig. 1 where the tool 144 isbelow the head of the blank and the tool 145 is beyond the head of theblank. After the tools have beenadvanced toward the blank in a directiontransverse to its axis the cam 149 causes the lever 147 to shift thetool block 143 in a direction par allel to the axis of the rotatingblank, first in one direction and then in the other so that the tool 144will size under the head of the blank or bolt and then the tool 145 willshave or finish the top of the head or the operation might be reversed.It will be noted that the movement of the tool 144 will tend to draw thespindle toward the right in Fig. 2 and this thrust movement may be takenup by the trunnion collar 82 engaging the stop 88 in the spindle head93.

The rollers 119 and 120 'act as stead ing supports for the rapidlyrotating b ank when it is being acted on by the cutting tools 144, and145. After the cutting operation has been completed the cutting toolsand the rollers are withdrawn and the blank may be dropped from thecollet and another put in place without interference.

The positioning plunger 74 tends to assure,

the blank bein so placed that when grasped in the collet t e head will.be in position to be between the cutters 144 and145 when they areadvanced to the blank.

The spindle head 93 may be adjusted along the bed of the machine towardand from the picker fingers and the tool slide 136to provide. foroperation upon blanks of difierent lengths; A- hand wheel 113 operatinga gear 114 engaging a rack 115 in a well mown way provides for movementof the spindle head. The usual bolts 116. are provided for holding thehead in any of its adjustments. The gear 90 may be held on the drivingshaft by 'a set screw so that it may be ad usted along the driving shaftas the indle head 93 is adjusted and thus the spin le may be rotated inwhatever position the spindle head may Likewise the drum 77 carrying thecams for operating the spindle and collet may be adjusted along the camshaft 15 and held by a set screw 78 so that the spindle may be roperlyreciprocated and the collet operated in any adjusted position the head93 may take.

Extending to the rear from the "head 93 are arms 118 between whichrotates the drum. 77 carrying the cams 76 and 97 for operating thespindle and the collet. When the cams have been set to properlycooperate to operate the spindle and collet the entire apparatus may beadjusted, along the bed of the machine so as to accommodate blanks ofvarious lengths by loosening the bolts the transfer carrier arm 36 willreceive a blank from the chute and deliver it into the picker fingers 54and 55 which will lower it into position to be sped by the collet jaws208 as the spind e 92 advances. The rollers 119 and 120 will thenadvance to support the blank. The tools 144 and 145 will then advanceabove and below the head of the blank. Lateral movement will be given tothe tools to cause them to attack the work. They and the rollers willthen recede and the finished blank will be ejected by the plunger 111 asthe collet opens and recedes with the moving spindle to clear the spacefor receipt of the next blank.
